Defensive publication

ABSTRACT

A POLYESTER COATING COMPOSITION COMPRISING A LINEAR POLYESTER CONTAINING TEREPHTHALIC ACID AND EITHER NEOPENTYL GLYCOL OR A MIXTURE OF NEOPENTYL GLYCOL AND ETHYLENE GLYCOL, CELLULOSE ACETATE BUTYRATE, A PLASTICIZER, AND OPTIONALLY A STABILIZER AND/OR PIGMENT. THE COATING CAN BE APPLIED TO A HEATABLE SUBSTRATE IN POWDER FORM AND CAUSED TO FUSE BY APPLICATION OF HEAT TO PRODUCE A THIN, SMOOTH, UNCRATERED SURFACE THAT EXHIBITS DESIRABLE RESISTANCE TO WEATHERING.
